To all -whom itjmoy concern:

f Beit known that I, HowARo W. BRACKEN, a eitiz'en of the United States, andl resident of Itlopedale, county of Worcesten'Stnte of Massachusetts, linve invented an Improvement in War Stop-Motions for Looms, of which the fol owing description, in connection with the accompanying drawing, is a specification, like characters on the drawing lo representing like arts. y

This invention as for Iits object the production of a novel and simple warp' stopmotion for looms, to effect automatical loom stoppage when n warp thread fails or l becomes unduly slack, an abnormally positioned detector at' such time engugin and arresting. the movement of a normal y vibrating' feeler. suitable means then'neting' to cause the operation of the loom stopping 2o mechanism. ln the embodiment'of my invention herein shown the detectors are in practice made of thin, Het metal strips, shown as arranged in two rows or banks between the lense-rods, a

feelervnormally vibrating below the detectors, and as said foelcr is arranged to coperate with a dropped'det'ector in either bank it follows that entli stroke of the feelol is 0. feeling;r stroke; Y(l,onsequently the means which on the one hand effects normal vibra tionof' the ieeler. and whieli on the other hand set-s in operation the stopping mecln|.- nism upon tln'arrest ot the feele't", must be so constructed and arranged to operate irrespeetive ot' the direetion o'f the stroke on wliieh the fes-ler is arrested. ln my present invention. the means whereby the feele'r is vibrat'ed norl'nally and tlie arrest oi the,

feeler vis reused to efl'ect .shipper release is 40 ot' a novel construction, und so aiglanged thatl it can he applied readily t'o 'a loom without vdhunonitwrintr or taking it down.' Thisis of material advantage in itself, for sncbmeans van be substituted I' or the feeler-A actuating and eontmllcd means in other forms of warp stop-motions with a minimum offexpenso, time and labor. These and ,other novel features ot'iny invention will be i fully deseril'ied in the subjoined specification and partieularly pointed out in the following claims.

harnesses I, and the lease-rods J, may be.90v

and are ofwell known or nsunl construction, and 'operate in a familiar manner, thelensefj rods ns herein shown being` sustained` li .v brackets. as K, erected one on each loom si e Y 'e andrarrying parallel' transverse buck-stop 96@ bars l. between whielr hang'the two'banks ot detectors M, N suspended from the warp* threads between the lense-rods. vThe detectors art` preferably. thin, tiat metal Strips enc-h longitudinally slotted for the reception of the warp-tln-ead and for n'sixp )ortm hay," or rod, as O, n .double-acting fee er P eing' by menne of j which usual means (not shown) is caused torl* lil nionnted on a rock-shaft Q sustained in the brackets K, ina manner well known to those skilled. .in the art, the feeler under normal conditions vibrating back and forth below '5 the lower'ends of the-suspended detectors f Various means have been devised heretofore for effecting the oscillation of the feeler rock-'shaft under normal conditions and for eii'ecting theA release of a Shipper or equiva- 10 lent device when vibration of Ithe feeler is arrested by engagement with an abnormally positioned detector, but so far as I am aware such means must be applied to the .loom during the setting up thereof, or by a 5 more. or less extensive dismemberment of the loom structure. In this invention I have obviated these objections and I willv now describe'the novel structure shown in the accompanying drawings.

The rock-shaftA Q, has applied toit an arm 1, and referring to Figs. 6 and 7 said arm is made with a thickened, U-shaped hub 2 formed by rs't boring;l and4 tapping the thickened end longitudinallyA and then slotting suchl tapped end transversely at 3, to form thefseat for the rock shaft-,the slotting leaving o posed segmental tapped p0rtions 4, 1 1. ber the arm is applied to the rock-shaft, Fig. 6,'a`setfscrew 5 is screwed into thojtappedhub, as shown in Fig. 1, a bteat Gon" the inner end of the screw bearing against the shaft and holding' said arm 1 fixedv thereupon, this construction ofthe detachable armpermitting it to be applied at any place on the shaft without removing the latter from its bearings.

The arm 1 ',ispivotally connected by a depending i'. with one end of a lateral arm 8 fast on a, longitudinally shiftable rockshaft -9 :at #the lower part of the loom, the

arm 8 boing enlarged-beyond the rodi-shaftY at 10 to substantially.. counterbalance they weightofthe link, the shafts Q and 9 thus' beingpositively connected and of necessity rockin together or n0t`at all. Said rockshaft is mountedin beari- 11, 11, Fig. 1, formed in a housing 12, 1n its front and rear walls, said housing .being conveniently made as a casting and havi a bulge 13 in the upper part of its rear wa 1, its open top being closed by a cap 14 secured by suitable bolts, as 15. This housing is sustained by any suitable part of the loom structure, and

herein I have shown it as supported by and:

suspended from the cam shaft. The side walls of the housing are provided wit-h half bearings 16, Fig. 2, to partly embrace the cam-shaft C, and the cap 14 has similar half hearings 17 which-are opposed to the bearings 16, and thus the cam shaft is completely encircled when the cap is boltedV to the housing. The housing is thus suspended from the cam shaft, and in a position well back inthe loom frame, out of the Way,

'and to prevent any rocking the wall of 'shaft 9, the follower and its rolls bcingfvery rear face, said hu having adjustably fixed rear face of the the housing is extendeddownward at 18," and has bolted to it a brace bar 19 extended frontward and bolted at20 to a part ofthe loom frame. Before the housing is positioned upon the cam shaft the latter has applied to it a wide faced pinion 21, made in halves-and rovided with annular cheeks 22 at itsl en s, the halves being connected and clamped xedly upon the cam shaft by clamping screws 23, Fig. 2, which are seated in recesses in one' half of each .cheek and enter suitable threaded holes in the complemental halves of the cheeks. When the honsino* is applied the sides thereof'just 'receive tile pinion cheeks freely between them, the sides of the cap 14 fttinginA av similar manner, as clearly shown by Fig. 2, so that no sidewise movement of the housing is pel'- l miatted, while the pinion and its cheeks rOff i tute freely within the housing and ite ca the bulge or swell 13 of the housin previging ample room for the cheeks att e; upperv part of the housing. f Hollow eidernal` bosses 24 on opposite sides of the housing i have extended through them a horizontal stud 25 below and parallel to the camshaft, fixed in position by set screws 26, I*`ig.A 2. Upon this stud is rotat-abl mounted the sleeve-like hub 27 of 'the eeler actuating cani 28, this cam being of peculiar shape, as best shownin Figs. 2 and 3', and in practice it is a skew or vWave cam, but its cylin asP drical rim has teeth 29 which mesh with and are driven by the pinion 21. Theimface of this pinion is made wide in order that it will alwa s remain in mesh with the cam tee-th 29 to e ect rotation of the latter, the feeler cam- 2 8 being wholly inclosed and protected by the housing.

It will be observed'that the opposite faces 1.05

of the cam 28 are the surfaces which exert al cam action, and this action is transmitted to rollsSO carried on the a'rmsof a yokelike follower 3l mounted to rockon-the' clearl shown in Fig. 4. On frontv face the ollower is provided with Vfshaped lugs 32 and a lon hub 33 extends from its upon it a collar 34, Fig. 1, t'o which is attached one end of a spring 35. Said sprin at its other end is attached to a U- bape bunter 36 fixedly secured by a set screw'' konto the shaft 9, to rock therewith and also to move as a unit vwith the shaft when the latter is moved longitudinally, as will be explained. Normally theI spring draws the..

-follower 31 forward with itslugs 32 .Seated in correspondinglg' shaped sockots 'in-the unter, see Fig. fsothat the follower and bunter will 4be rsymrneatri-I callyv positioned with respect to their `com- 'mon support, the shaft 9, and said parts will be yieldmgly connected. As the cam 28 is revolved the follower and bnnferwill. iso

-and protecting them from` lint, dust and dirt, irrespective of that partof 4the loom to which saidhousing is attached. At the same time'the suspension of the'housing from. the cam shaft locates the housing and its contents in the lower part of the loom frame and out of the way of other parts of the loom instrumentality.

The spring 35 isalight spring, suiciently strong to slightly vmore than overcome fric; tion of and normally connect the follower and the that when a detector arrests the vibratory movement of the feeler the engaged detector has to sustain very slight pressure at the time the bunter and follower are disconnected. Consequently there is practically no tendency to bend or strain a detector.

. By locating the normally oscillating, longitudinally movable member or shaft 9 substantially at right angles to the cam shaft, and also at the lower, rear part of the loom frame it and adjacent devlces of the stopmotion can be set back as close as possible to the warp beam,

for the occasional longitudinal orvendwise movement of such member 9 to effect loom stoppage is frontward, hence awa from the warp beam.

Various changes or modifications in details of construction and arrangement may be made by those `skilled in the art without departing from the spirit and Scope of my 4 invention as set forth in the claims hereunto annexed.
